the vertices of the mesh on which the m aterial is applied with the same amount of

displacement. To have more control over the localities on the m esh, w e can supply a

texture through a Texture Sample input. If a texture is supplied to the World Po-

sition Offset channel, the effect of displacement will be calculate d from the texture

and applied to appropriate vertice s and location on the mesh.

Figure 4.14 shows how different values on the World Position Offset channel

affect the geometry of a mesh directly from the material. In this figure, the object on

the left has a mater ia l with no
